How pollution is changing the ocean's chemistry

As we keep pumping carbon dioxide into the atmosphere, more of it is dissolving in the oceans, leading to drastic changes in the water's chemistry. Triona McGrath researches this process, known as ocean acidification, and in this talk she takes us for a dive into an oceanographer's world. Learn more about how the "evil twin of climate change" is impacting the ocean -- and the life that depends on it.

The Pacific Marine Environmental Laboratory
The Pacific Marine Environmental Laboratory has a list of important links with extra information on ocean acidification here, with a more detailed description of ocean acidification and associated research. Scientific knowledge about the oceans is constantly growing and improving so it is best to look at recent research that has incorporated the latest findings on the topic.

20 facts about ocean acidification
Ocean Carbon and Biogeochemistry Project has a nice document about the 20 facts about ocean acidification that are clear and concise, but with more detailed information than I was able to go into in the TED talk. It also has links to some nice videos and teaching materials for educators.

"Oceans in a High-CO2 World"
Every 4 years, scientists carrying out research in all aspects of ocean acidification get together to share their findings in a symposium called "Oceans in a High-CO2 World." The policy report generated after the 2012 symposium is here
